Image for a portion of a display screen



The FIGURE is a front view of an image for a portion of a display screen showing our new design.

The broken line drawings of the square and rectangles, as well as the display screen are for illustrative purposes only and form no part of the claimed design. The broken line circle and the area within, form no part of the claimed design. 

We claim the ornamental design for an image for a portion of a display screen, as shown and described.
